摘要
针对污水处理厂进水有机污染物低，活性污泥老化比较严重，导致活性污泥絮凝性能降低，出水水质恶化的情况，通过后投加聚合氯化铝铁的方式，改善活性污泥的絮凝沉降性能，从而实现改善出水水质的目的。
Activated sludge aging more serious at low influent organic pollutants of wastewater treatment plant ,resulting in reduced sludge flocculation and effluent quality deterioration. In order to achieve the purpose of improving water quality by adding PAFC at the back of biochemical tank to improve the activated sludge flocculation and settling characteristics.
